Problems solved by technology

However, as the vehicle load continues to increase, this traditional single-leaf spring balance suspension cannot well solve the contradiction between the vehicle's no-load and full-load conditions.
That is, under the condition of no load, the total mass of the vehicle is relatively small, the stiffness of the leaf spring is too large, and the comfort of the vehicle is too poor; while the total mass of the vehicle is relatively large under the condition of full load, the stiffness of the leaf spring is too small to bear too much the weight of

Embodiment Construction

[0011] The balanced suspension leaf spring of the embodiment is formed by connecting the main plate spring and the secondary leaf spring so as to increase the bearing capacity. The balance shaft housing 4 and the balance shaft 3 are connected by bearings, and the balance shaft housing 4 is rotatable; the main plate spring 1 of the balance suspension and the auxiliary plate spring 2 of the balance suspension are respectively fixed on the top and bottom of the balance shaft housing 4 by saddle bolts 5 In the two grooves; the upper leaf spring slide seat 6 and the lower leaf spring slide seat 7 are respectively fixed on the top and bottom of the two front and rear bridge tubes, and the two ends of the main plate spring 1 of the balance suspension are respectively inserted in the upper leaf spring slide seat 6 In the cavity; two ends of the balance suspension secondary leaf spring 2 are respectively inserted in the cavity of the lower leaf spring slide seat 7.

Abstract

The invention relates to a design method of a balancing suspension device which is used on various middle and heavy type load vehicles, in particular to a design method for a balancing suspension device of a main and auxiliary dual plate spring structure. The invention is characterized in that the balancing suspension plate spring is formed by adopting the connection of the main plate spring and the auxiliary plate spring so as to improve the bearing ability. The device has small suspension stiffness and good driving comfort when in empty load, and has large suspension stiffness and strong bearing capacity when in full load, so two different working conditions of the empty and full load are satisfied.

Description

technical field [0001] The invention relates to a design method of a balanced suspension device used on various medium and heavy load vehicles, in particular to a design method of a balanced suspension device with a main and auxiliary double leaf spring structure. Background technique [0002] Traditional balance suspensions are all single-leaf spring structures, that is, the middle of the leaf spring is fixed on a balance shaft. The two ends are supported on the front and rear axles, and the force is transmitted to the ground through the tires on the axles. This kind of balanced suspension can well distribute the forces on the front and rear wheels evenly, so it is widely used. But along with the continuous increase of the load capacity of the vehicle, this traditional single-leaf spring balanced suspension cannot well solve the contradiction between the vehicle's no-load and full-load conditions. That is, under the condition of no load, the total mass of the vehicle is r...
